plugin to check whether all the tasks are in closed state RRS feed

  • Question

  • Hi,

    I have a lookup field named "stage".. which contains s1, s2 and so on.. once i select s1.. the related tasks are shown in a subgrid.. Only if all the tasks are in closed state, then only i should be able to change the value of field "stage" from s1 to s2 etc. if any of the task is open then i should not be able to select another stage..

    Which means that the field "stage" should be disabled if any one of the task is in open state..

    I need to do this using a plugin.....
